BALlNG-PRESS.

SPECIFICATION formingpart of Letters Patent No. 625,436, dated May 23,1899.

Application filed May '7, 1897. Serial No. 635,525. (No model.)

To all whom it may concern.-

Be it known that I, PETER K. DEDERICK, of Albany, in the county ofAlbany and State of New York, have invented certain new and usefulImprovements in BalingPresses; and I do hereby declare the following tobe a full, clear, and exact description of the same, reference being hadto the accompanying drawings, forming part of this specification, and tothe letters of reference marked thereon.

'This'invention relates to improvements in baling-presses, the novelfeatures being applicable mainly, though not exclusively, tobaling-presses of the vertical or upright type, and more especially tothe presses of this type in which the traverser or follower movesupward, condensing the material against the head or top of thepress-case.

The invention has for its objects to improve the detail construction ofthe press, wherebyit may be handled and manipulated with greaterfacility, to reduce the weight and at the same time strengthen theconstruction of the framing and power, thereby permitting of a greatercompression of the material, and to provide a double press or press forforming duplicate bales simultaneously which shall embody the desirablefeatures mentioned.

Referring to the accompanying drawings, Figure 1 is a perspective viewof a balingpress embodying my present improvements with the heads anddoors on one side open. Fig. 2 is a vertical section showing parts inelevation. Fig. 3 is a perspective view, partly in section, showing thearrangement of the shippers forautomatically arrestingthe powermechanism at each extreme of its movement. Fig. 4 is a detail showingone of the reverse retainers. Fig. 5 is a similar view showing anotherform of reverse retainer. Fig. 6 is a similar view showing severalmodifications of reverse retainers.

Like letters of reference in the several figures indicate the sameparts.

In carrying this invention into practice I preferably provide a framingwhich will support not only the power mechanism proper and press-case,but also the driving-power mechanism. Thus the only connections whichhave to be made are with the prime moveror engine through the medium ofbelts or equivalent devices. For this purpose Iprovide sills A, adaptedto support the press-case B, and also extensions A, upon which thedriving mechanism is mounted, as will be presently described, andadapted to be connected with the power mechanism through the end wall ofthe press-case in the ordinary manner. The press-case in the presentinstance is preferably substantially rectangular and is formed byupright planking suitably sup ported by appropriate bracing and having011 each side near the top swinging doors or sections 0.

In the construction of press shown two bales are adapted to be formedsimultaneously, the press-case for this purpose being dividedtransversely by a partition D, and the doors or swinging sections 0,above referred to, are preferably connected together on each side of thepress-case, first, by a girder at the bottom having suitableintermediate and end bearings o and constituting the hinge or pivotalsupport for the doors or sections, and, secondly, by a top girder G, extending the entire length of the press-case and having notches orrecesses c at the ends for the reception of the ends of transversegirders 0 The girders thus form a complete encircling band around thetop of the press case and are held in their relative positions with thedoor 0 closed'by hooks or catches E, pivotally mounted on the press-caseand adapted to automatically drop over and hold the longitudinal girdersO, as will be readily understood from an inspection of Fig. 1.

The traverser or follower working vertically in the press-case islettered F, Fig. 1, and it is preferably formed in the main by two rel*atively thin metallic plates f, projecting through narrow slots f in oneend of the cas= ing and passing through similar slots in the centralpartition D. These plates support the pivotal bearings for the upperends of the power-levers, and upon them is built the face of thefollower F, which latter is usually made up of heavy wooden planks andgirders or timbers bolted alongside of the plates f, be* fore referredto.

The power mechanism in the present instance (see Fig.2) consists,preferably, ofthree pairs of jointed toggles G, one of the pairs, asshown, that nearest the left-hand end,be-

ing extended in the form of a toggle-lever G and adapted for theconnection of the driving mechanism at its lower end. At or near thejoints of the respective toggles they are connected together bylongitudinal bars or connections G whereby they are caused to move inunison and to raise and lower the traverser while maintaining it in itshorizontal position. It will be particularly observed that one pair oftoggles is located in each of the press-chambers and the other pair oftog? gles is located entirely outside of the presscasing. Thus there isno necessity for cutting away the sides of the press-case for thepassage of the knuckles. The lower togglearms of the pairs G are madedouble-that is to say, there is a single upper toggle-arm and two lowertoggle-arms jointed together at the center-and the lower toggle-armshave their lower ends separated somewhat widely and pivotally mounted inmetallic bearing blocks or boxes H, suitably secured to the frame,andalso adapted to accommodate the lower ends of vertically-disposed rodsextending to the top of the press-case and adapted to hold the headsagainst which the pressing operation is performed. In the preferredconstruction the lower ends of the rods are provided with eyes, throughwhich the pins forming the pivots of the toggle-arms pass, whereby, aswill be readily understood, the entire strain of the pressing operationis taken up in the powermechanism heads and connecting-rods rather thanby the press-frame itself, and consequently little or no verticalframing, such as has been previously necessary in all upright presses,is now found necessary. The rods extending up from the centraltoggle-arms pass up in the partition D and can be seen in Fig. 1,beinglettered I, and at their upper ends they pass through a casting 1,above which they receive plates or washers t' for retaining the castingin place. Said casting, as in my application, Serial No. 621,856,constitutes the lock or retainer for the inner ends of the heads K. Theheads Kare themselves mounted upon the upperends of sway bars or rods Itat each end of the press, which rods k extend down and are connected tothe bearings of the toggle-joints, as before explained. By mounting theheads in this manner on the upper ends of long sway-bars and providingstops, such as the cross-planking 7.2, for preventing the heads andsway-bars from assuming an angle with relation to each other less than aright angle said heads are caused when swung open, as shown in Fig. 1,to rise up away from the edges of the press-case and when swung back tomove down closely thereon, with their forward ends beneath the castingI, before referred to. In addition itwill be observed that the operatorhas little or none of the weight of the head to lift in opening orclosing the press-case, as the heads swing baclgand from the very startthe weight necessary to be lifted becomes less and less,

owing to the fact that the heads move farther and farther over theirpivotal points.

To limit the outward swing of the heads, stops or limiting-rods K arepreferably connected with the press-case at each end at a pointproximately midway of its height, and at the end of the press throughwhichthe traverser projects the transverse girth, which must be dividedfor the passage of the traverser end and power mechanism, is held inplace and the requisite strength afforded by a metallic connection L,Fig. 1, slotted or cut away on the inner side for the accommoda tion ofthe power mechanism and end of the traverser.

The sway-bars at the left-hand end of the press, Fig. I, extend downoutside of the press-case as at the right-hand end; but inasmuch as thepivots for the toggle-arms at this end are located within thepress-case, Fig. 2, it is necessary or desirable that the ends of thesway-bars should be pivotally connected to links or short connectionsextending through the wall of the press-case diagonally upward andhaving at their upper ends eyes or other suitable form of pivotalconnection for the lower ends of the sway-bars.

In operating presses of this character it is customary to close the sidedoors, leaving the top or heads open, throw material into thepress-case, and then tramp it down as closely as possible upon thetraverser, which is then at the bottom of the press-case. The insidesurface of the press-case is very smooth owing to the friction of thepressed material against it and to the fact that it is made so toprevent undue friction, and consequently it the material being baled isat all elastic the amount which can be tramped into the presscase islimited, practice demonstrating that as soon as the operator steps fromone point to another the material at once returns to its normal heightand no more material can be gotten into the press-case. The result isthat in order to secure sizable bales the press-case must be made undulytall, and with a View to overcoming this difficulty I now locate in thewalls of the press-case what I term reverse retainers-that is to say,retainers which operate reversely to the action of the traverser. Withsuch retainers when the materialhay,for instance-is tramped down it isretained against springing upwardly, and practice hasdemonstrated that avery much larger quantity can be tramped into the press-case in thisway. \Vhen the heads are returned to place and the end of the presscaseclosed,these retainers may be withdrawn automatically or otherwise andthe pressing operation proceeded with as ordinarily.

In Fig. 4 I have illustrated in section and diagram matically one formof reverse retainer which consists, essentially, of a series ofinwardly-projecting teeth M, having their holdin g-faces set to hold thematerial reversely to the action of the traverser and united or formedon bars, such as m, and at the lower ends such bars are provided withinwardlyprojecting feet or extensions M. The bars in and teeth carriedthereby are movable vertically to a limited extent, being supported bytransverse pins 'm, working incurved or diagonally-arranged slots m inguides or castings m secured to the press-case, and consequently whenmoved upwardly said teeth.

are withdrawn from the inner surface of the press-case, leaving saidsurface practically smooth for the pressing operation. The feet orextensions M before referred to serve as a means for insuring theprojecting of the teeth within the press-case when the hay is trampedtherein, as the weight of the hay upon said feet or extensions willforce the rods m downward. Openings may be formed in the traverser forthe passage of these extensions, or, if desired, the extensions may passunder the traverser in position to be struck thereby when the traverseris in its lowermost position; but when the traverser commences to moveupwardly this pressure is relieved, and the first movement of the hayupwardly causes the teeth to automatically withdraw, as beforeexplained.

lVhere the reverse retainers are located in the sides of the press-case,they should also extend through the doors O, and for this purpose theyare centrally divided and the two sections united by a strip or otherflexible connection m", which will permit the doors to swing open, aswill be readily understood.

If desired, the reverse retainers may be mounted upon a support by shortpivoted links 0, Fig. 5, and to secure the necessary movement of theretainers they may be connected at their lower end with a lever O,pivoted to the frame and constituting one of the links and having itsforward end 0 extended beneath the hay or, preferably, as shown, beneaththe traverser itself, While to secure a positive upward movement orrelease of the retainers the lever may be provided with a shorterextension 0 adapted to rest above the traverser when the latter is inits lowermost position, as shown in this figure, and adapted when thetraverser moves upward to be struck thereby and turned to the positionindicatedin dotted lines. It is retained in this position by friction orby a spring 0 until the traverser again descends and turns it down tothe position shown in full lines.

Obviously many difierent forms of retainers may be employed toaccomplish the result aimed at, it only being necessary that they shouldoperate reversely to the action of the traverser, and I have shown inFig. 6 an upright or side of a press-case having three different formsof retainers thereon, that at the top consisting of a spring-pressedpivoted segment P, held in place by a spring 1) and adapted to benormally projected within the casing thereby, so as to yield underexcessive pressure, as when the traverser is traveling upwardly, but ofsufficient strength to retain the hay againstthe traverser when trampednaled in an arm or link Q pivoted at a point outside of the press-caseto a bracket or other suitable support Q and held against rotation inone direction by a pawl Q for retaining the hay when tramped. The linkor arm Q is held down by a spring Q but will yield upwardly as thetraverser rises, the strength of the spring Q being sufiicient, however,to retain the hay, as before explained.

Obviously retainers may be located in the side Walls of the press-caseWherever found necessary or desirable to hold the hay down while beingtramped, and hence I do not wish to be limited either to the specificform of the retainers or to the particular location thereof.

By reference to Fig. 2 it will be seen that the driving mechanismconsists of a drum R, journaled in the frame or sills and having adoubled chain or flexible connection extend-- ing loosely through a hole9 in the lowerend of the extended toggle-lever G to render and equalizein winding, so as to draw said lever outwardly and raise the platen whenthe chain or flexible connection is Wound on the drum. For convenienceand to hold the chain in its proper position or in line with the lowerend of the lever it is preferably passed around a roller R, journaled inthe sill-framing, with its lower side or periphery approximately on alevel with the lower end of the lever. The drum is provided at one endwith a wormwheel R with which a worm R meshes, the latter being mountedon a shaft extending longitudinally of the frame and carrying threepulleys S S S the central pulley S being fast on the shaft,'whi1e thetwo outside pulleys S and S are loose and adapted to receivedriving-belts running in opposite directions or one straight and theother crossed. When the belt is shifted to the central pulley, the

traverser will be moved upwardly, and when the opposite belt is shiftedto the central pulley the traverser will be moved in the oppositedirection, and in order to secure an automatic stoppage of the traverserin each direction when the traverser is moved to the limit of its strokein either direction advantage is taken of the movement of thetogglelever to move belt-shifters, which will move the belts to theloose pulleys.

Referring to Fig. 3, it will be seen that I provide two belt-shifters,(lettered T and R which belt-shifters are connected at their ends tohand-levers T and R pivoted, respectively, to the sills or framing ofthe press at any suitable points. From these hand-levers T and R rods Tand R extend to oppositely-arranged pivoted levers T and R The lever Tis in position to be struck and moved by the power mechanism ortoggle-lever when at the lower extreme of its movement and the lever Ris in position to be struck and moved by said power-lever when at theupward extreme of its movement. Such movements of the levers T and Bwill cause the shifting of the belt to the loose pulleys, therebystopping the operation of the power mechanism until it is again put inmotion by moving the hand-levers T or R Having thus described myinvention, what I claim as new is 1.
